WORLD champion Lewis Hamilton admits the hard work starts here if he is to retain his F1 title.

The 24-year-old McLaren Mercedes driver from Tewin took third place around Albert Park in today's season-opening Australian Grand Prix.

It was a terrific drive by the Herts hero from 18th on the grid, but owed more to other people's misfortune than the McLaren's actual race pace and drivability.

Hamilton admitted afterwards that the car is not up to spec just yet.

But he said every effort is being made by the team to make it as competitive as quickly as possible.

"Since we've come here we've not really improved the car as such, we've made some set-up changes but the car is what it is at the moment," said Hamilton after Sunday's grand prix.

"But we've got a lot of work going on back at the factory.

"Hopefully step by step we will continue to score points and catch people up."

The second race of the season - the Malaysian Grand Prix - takes place next Sunday in Kuala Lumpur.
